<h2><b>Scatter Plots</b></h2>
<p class="plaintext">
This section describes how to draw a scatter plot and refine the display with controls over colors and axis labels. The commands are:
<p><code>set gxout scatter<br>
display exp1;exp2<span class="italic"><;exp3></span></code>
<p class="plaintext">
Where:
<ul>
<code>exp1 </code>
<span class="plaintext">A grid expression that determines the position of the scatter points on the X axis</span><br>
<code>exp2 </code>
<span class="plaintext">A grid expression that determines the position of the scatter points on the Y axis</span><br>
<code>exp3 </code>
<span class="plaintext">A grid expression that determines the color of the points in the scatter plot (</span><span class="red">GrADS version 2.0.2+</span>)<br>
</ul>
<h3>Usage Notes</h3>
<ol>
<p class="fineprint"><span class="plaintext">The third argument to control the colorization of the points in the scatter diagram is new in GrADS version 2.0.2. </span>Use <code><a href="gradcomdsetclevs.html">set clevs</a></code> and <code><a href="gradcomdsetccols.html">set ccols</a></code> to control the range of values and color for each level. When using colorization of the scatter plot, if any of the color numbers is < 0, no points will be drawn for that level.</p>
<p class="fineprint"><span class="plaintext">After a display of a scatter plot, GrADS will return four numbers: the
min and max of the X axis values, followed by the min and max of the Y axis values.</span></p>
<p class="fineprint"><span class="plaintext">Use the <a href="gradcomdsetvrange.html"><code>set vrange</code></a> command to specificy the min and max of the X axis values if you do not wish to use the defaults that GrADS selects. <br>
Use the <a href="gradcomdsetvrange2.html"><code>set vrange2</code></a> command to specificy the min and max of the Y axis values if you do not wish to use the defaults that GrADS selects. <br>
</span></p>
